Storage Redundancy (1 / 16):

Your company has an application that generates a significant amount of log data. This log data can be reproduced easily and is not subject to stringent data governance laws. However, your company wants to ensure that the data loss possibility is minimized while keeping costs controlled.

What Azure storage redundancy option would you recommend to your company for storing their log data and why?
How would the suggested redundancy type handle data loss scenarios?
If your company decided to go for Geo-Redundant Storage instead, what potential issues might they encounter?

Answer:

For your company's scenario, Locally Redundant Storage (LRS) would be recommended. LRS would ensure three copies of their data exist in the same data center, providing durability and redundancy. Since the log data can be easily reproduced, this option would be cost-effective as well.
In a data loss scenario, LRS would provide resilience by having three copies of the data. If one copy fails, the data can still be accessed from the other copies.
If your company opted for Geo-Redundant Storage, it would increase their costs. In addition, they may encounter potential consistency issues since GRS replicates data asynchronously to a secondary region, and in the event of a failover, the data in the secondary region might be slightly out of date compared to the primary region.
